I got one of these earlier last year so I didn't have to keep running to the PSO to use his spinner on 6 balls every week. { he allows FREE use of spinner, very lucky here!} This system does well for Maintaining/ changing surface but NOT resurface. Polishing is not as easy either, can't get the deep burn like a spinner. Yes its quick & much easier than by hand but it ain't no replacement for a ball spinner. More like in addition to, great at the lanes where spinners not allowed.
